learners according to the CAPS document. Definition Price (2001)‚ state that place value refers to our base-ten system‚ where each digit in a number represents a partial amount‚ this amount is determined by the structure of the number and the position of the digit in the number. In the base-ten system the position of a digit represents its value‚ therefore each digit has its own value in relation to another written symbol. This concept can be very easy to understand or it can be very complex‚ it

This is because 16 bits provide four four-bit locations. The lowest (right most) and two middle 4 bits can each store any number from 0 to 9. In the highest (left most) 4 bits‚ one bit is used for the sign‚ leaving 3 bits for digits. These 3 bits can accommodate numbers between 0 and 7. 4) a) 15675 is a positive

Montessori way of teaching mathematic is truly a wonderful and interesting way to learn the concepts of mathematics. Mathematic is very important for our daily life. Mathematic relates to numbers and numbers are around us all the time‚ so it is very important to introduce numbers to the child at very early age‚ but before you introduce numbers it is important to lay a strong foundation of practical life activities and sensorial training to the child. Practical life activities allows the child to

One interesting way (found in some books) is to take the two left-most digits‚ multiply the left digit by 3 and add it to the second digit. Replace these two digits with the result. Then we can keep repeating‚ always dealing with only the two left-most digits‚ until we end up with a small number which is either divisible by 7 or not. Pretend we have a two digit number‚ 10x+y. We multiply the left digit by 3 and add the second digit: 3x+y. All we did was just subtract 7x. If 3x+y is divisible by 7‚ then
